What each ingredient does

Butter
Provides fat and rich flavour, and helps make the sauce smooth and glossy.
Flour
Thickens the sauce as its starch swells in the simmering liquid.
Water
Forms the liquid base that the butter and flour are combined into.

The step that matters

Whisking in the flour. Adding flour to hot liquid without whisking can form lumps, because starch clumps before it disperses. Whisking steadily while adding it keeps the sauce smooth before it thickens.
